Measuring transducer EP8527/14, 15, 18, 19 - a device for converting alternating current line-operate and congestion in a standardized output AC signal.
Measuring transducer EP8527 / 3, 13 - a device for converting linear voltage AC operation modes and modes of congestion in a standardized output AC signal.
Devices EP8527 / 1, 2, 4-12 is monaural products. The number of channels in type converters 3, 13-19 from one to four (on request).
Feature types of devices EP8527 1, 2, 4-12 is that they are single-channel. Type converters 3, 13-19 have from one to four channels (on request).
Measuring converters are often used in the information-measuring system for transmitting information to the input of high-speed digital oscilloscope (for recording and analysis of emergency operation), do not require an additional power supply.
In the devices is a function of galvanic isolation between the input and output circuits for each channel, as well as any link between the chains and the chains of the other channels.
Measuring range input: 0-5A, 0-400V.
Measuring range Output: 0-5, 0-5 -6.5, 0-5 , 100 mA.
Accuracy classes in operation span the input signal (in overload the input of the measuring range) for various modifications of the inverter EP8527:
- Types 1, 2, 12, 16, 17 - 1.0;
- Types 3, 13 - 0.25 (0.5);
- Types 4-11 - (2.0);
- Types 14, 15 - 0.25 (0.5);
- Types 18, 19 - 1.0 (2.0).
The range of the input and output devices from 45 to 55Hz.
For speed measurement limits of permissible basic error as a percentage of the value of the normalizing input signal are shown in Table 1.
Table 2 according to the modification of the converter fed characteristics of input and output signals, the load impedance.
Table 2-1. Har akteristiki input and output signals, the resistance of the load.
Table 2-2. Har akteristiki input and output signals, the resistance of the load.
The value of the WMO -stand resistance transducer EP8527 when the input signal is equal to the final value of the measuring range of the working mode is:
- For type 3 - at least 55kOm;
- For type 13 - at least 9kOm;
- For types 14, 16-18 - less than 0.2 ohm;
- For types 15, 19 - not more than 0.01 ohms.
As for types 1, 2, 4-12, due to the lack of input circuits, the installation of which is performed at potrebitelyai depends on the cable cross-section passing through a hole in the unit as a primary winding, the input impedance of the transducer is not standardized.
Time mja operating mode setting device not more than 5 minutes.
Time mja continuous operation type converters 1, 2, 4-12, 14-19 is not limited at nominal values of the input signal shown in Table 2, with respect to types 3, 13, uptime is not limited by the maximum values of the input signal reloading modes in the table. Continuous operation type converters 4-11, 14, 15, 18, 19, with maximum values of the input signal reloading conditions shown in Table 2, no more than 5 minutes to 2 hours repetition.
Number overloads to 60A input current without damage to equipment types 1, 16, 17 - two, and two types of devices, 12 - to 300 1 sec intervals between overloads 4:00.
Apparatus Types 3, 13 is maintained without damaging overloads nine input voltage equal to 150% of the nominal value, duration 0.5 s intervals between 15 overloads. The output signal in case of overload does not exceed the maximum load on the 15V - AC voltage (rms).
In Table 3, the values allowed filed additional reduced errors caused by changes in the influencing factors of the normal range
a) to -30 ° C and +50 ° sleep every 10 ° C with ambient temperature changes from (20 ± 2) ° C for three types of transmitters 13, 14, 15 and (20 ± 5) ° C for type 1, 2, 4-12, 16-19:
